        <h2>Usage notes</h2>
        <p><strong>Backup modes</strong>: An app can be backed up with only its apk, only its data
            or both. An app not currently installed can only be restored if the apk is present.
        </p>
        <p><strong>Delete backup</strong>: Deletes the backup files for the chosen app.
        </p>
        <p><strong>Uninstall</strong>: Somewhat more aggressive than a normal uninstall. In addition
            to doing a normal uninstall via android commands, uninstalling from OAndBackupX deletes
            files the app might have left over in /data/app-lib/.
        </p>
        <p><strong>Enable / disable</strong>: Uses the android script `pm` to enable or disable an
            app. Disabling an app removes it from the normal user interface without uninstalling.
            This can be used for enabling or disabling an app for muliple users at a time (if the
            device has multiple users enabled). Users are identified with an id. 0 is the first user
            (owner).
        </p>
        <p><strong>Multiple users</strong>: Multi-user is still somewhat experimental but should
            work. When restoring in a multi-user scenario, `pm install -r $apk` gets called and
            subsequently the app is disabled for every user who has the app listed in
            /data/system/user/$user/package-restrictions.xml (unless the app is listed as
            enabled="1").
            <br />
            This can create problems for users installing the same app at some later point, but is
            necessary to prevent the app from being installed to all users at the same time. The
            context menu has an option to enable or disable apps which can be used if other users
            become unable to use a specific app due to disabling on restore.
            <br />
            Enabling and disabling only works after an initial install (not necessarily from
            OAndBackupx) or restore of the app.
